From the warning at the top, what is big-endian architecture? --[[User:Braydon|Braydon]] 16:28, 4 October 2008 (UTC)

Revision as of 16:28, 4 October 2008

Is there any particular reason for the "NOTE: You cannot transfer more than 2MB of data into RAM using this method"? I had no problem transferring a 29 MB file to the RAM. I recognise 32 MB (size which latest rootfs builds have crossed recently) will be a problem because the u-boot's stack or other section starts at 0x34000000. Moving the RAM download address in DFU to 0x31000000 seems to work around that though. balrog 14:37, 12 June 2007 (CEST)

I can verify that the latest dfu-util does not work with big-endian (host running dfu-util).
Transfer size is obtained as 0x0010 instead of 0x1000.
Oh, I see that the usb wire encoding convention is apparently little endian, not network byte order. :(
Is transfer size the only one that needs to be swapped? It seemed to be the only one specifically marked with a Endian-todo comment. Don 17:41, 31 July 2007 (CEST)

Does anyone know where to find a DFU Util for Windows/Win32 (Windows XP etc.)? The DFU Utilities for Windows (DFU Wizard mostly) see to only come in customized packages with the firmware they are supposed to upload. There seems to be no "dfu.exe" freely available which one could use to flash the Neo1973 via USB. If you find anything, please put a link into the "binaries" section. hhf423 13:34, 12 August 2008 (CEST)
